A rendering of the completed project was prepared for approval by the CDOT and local agencies. 38 | ASPIRE , Spring 2008 The residents and visitors at the world- class ski resort of Aspen, Colorado, have waited years for the 'Entrance to Aspen' project to be completed. This consists of the reconstruction of State Highway 82 as the primary access road and one of only two routes into the town from the west. The highway crosses the wide and deep Maroon Creek basin at the town limits on the oldest bridge in service on the Colorado state highway system. Due to its historical significance, the existing bridge is listed on the National Register of Historic Places. Originally constructed as a railroad trestle bridge in 1888, the Colorado Midland Railroad Bridge became the property of what was then called the Colorado Department of Highways in 1927. The Maroon Creek Bridge was converted for highway use in 1929 and widened in 1963 to its current width of 30 ft by adding outrigger struts to the original A-frame trestles. Since then, the timber bridge deck with asphalt has been replaced once and repaired several times. To this day, the structure continues to require high maintenance profile Ma R oon C ReeK BRiDge RePlaC eMenT / StAtE H IGHWAy 82, A SPEn, CoLoRADo ENGINEER: Parsons transportation Group, Denver, Colo.
